trace-cmd: Make the trace-cmd target buildable out-of-tree
This patch allows the trace-cmd app to be buildable out-of-tree when the 'O'
variable is set at command line while invoking make.
At this stage, when the 'O' variable is set, the out-of-tree build will fail
for some targets like 'gui' (as it *already* happens on the master branch): with
this patch the final goal of a fully working out-of-tree build gets closer.
In successive steps, the remaining Makefiles will be made to support out-of-tree
builds, until everything works.
NOTE: the regular in-tree build of all targets clearly continues to work.
